IMPROVEMENT IN BROADCAST SEEDING-MACHINE.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, SAMUEL THOMSON, of Osceola, in the county of Polk, and State of Wisconsin, have` invented a new and improved Broadcast Seeding-Machine; and I dofhereby declarethat. the following is a. full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part of this specification. i e This invention relates to a new and improved seeding-machine, of that class which are designed to-sow seed in a broadcast manner, and in greater or less quantity over agiven area, as may be required.

The invention c onsists of a seed-box or hopper, applied to an axle provided with ordinary wheels, and having a revolving cylinder placed in front, containing seed-cells, said cylinder being arranged in such relation with the discharge-aperture, at the bottom of the hopper, that the seed, as theimplement is drawn along and the cylinderV rotated, willhe taken up by the cylinder, and discharged upon a scattering-band, from which itis discharged,

upon the ground in a broadcast manner. In the accompanying drawings-- Figure 1 is a side sectional view of my invention taken in the line n: as, g. 2. Figure 2, aa plan or top' view ofthe same.

, Similar letters of reference indicate corresponding parts.

A represents an axle, having a wheel, B, on each end of it, and a; draught-pole, C, attached. D is the drivers seat, placed centrally on the axle at tho rear ofthe draught-p`cleg E is a. seed-box or hopper,` which is secured tothe front side ofthe axle, extending the wholelength of the same. This seed-box or hopper is of V-t`orm in its transverse section, and an opening, a, is allowed at its lower end, through which the seed passes upon a horizontal bottom plato, b, as will he fully Yunderstood by referring to fig. 1. F is a cylinder, which is placed and works in the angle formed by the bottom plate b, andthe front side of' the seed-box, as shown clearly in iig. 1. This cylinder may he constructed of wood or metal, and it hasrecesses or` seed-cells c placed in its periphery. If the cylinder be of wood, these recesses or cells should be wholly or partially lined with metal, in order to prevent wear or splitting. Themylinder, F, as the implement is drawn along, is rotated in the direction of the arrdw, 1, by a belt, d, from a. pulley, e, attachedconcentrically to one ofthe Wheels, B, and the 'speed ot' rotation may be increased, when desired, by slipping one or more rings over the pulley,-e,.which of course enlarges said pulley.

It will be seen, from the above description, that as the implement is drawn along, the seed which passes through the opening a, at the lower part of the seed-box, will be taken up bythe cells in the cylinder F, and

discharged from said cells as the latter pass over in front of the axis 'of the cylinder. The seed, as itis discharged fromthe cylinder, falls upon an inclined board, Gr, which serves as a scatterer, and causes the seed to bef-discharged uponthe ground in a broadcast manner.

By varying the diameter ofthe pulley e to regulate the speed of rotation of the cylinder, F, a. greater or u less quantity of seed may be sown over a given area, as desired.

The devicemay be .attached to the rear of any ordinary wagon or vehicle, or a. team may be hitched directly to it. y

I claim as new, and desire to secure by Letters Patent- The rotating seed-discharging cylinder F, in combination with the seed-box or hopper E, having au open-` ing, a, at its lower part, the bottom plate b, and the scattering-hoard G, all arranged to operate substantially SAMUEL THOMSON.
